* roqvideoenc: set enc->avctx in roq_encode_initAndreas Cadhalpun2015-03-11
| | | | | | | | | | | So far it is only set in roq_encode_frame, but it is used in roq_encode_end to free the coded_frame. This currently segfaults if roq_encode_frame is not called between roq_encode_init and roq_encode_end.

* rtpdec_vp9: Drop extra sanity check for size of input packetVittorio Giovara2015-03-11
| | | | | | | | In this case len is always at least 1, since it is checked against RTP_VP9_DESC_REQUIRED_SIZE + 1 and then it is reduced by RTP_VP9_DESC_REQUIRED_SIZE before entering the has_pic_id check. Bug-Id: CID 1270811
* mp3: Properly use AVCodecContext APIVittorio Giovara2015-03-11
| | | | | | | Rather than having an unitialized context on the stack, allocate it with defaults and free it when unneeded. CC: libav-stable@libav.org

* mlpdec: support TrueHD streams with an Atmos substreamHendrik Leppkes2015-03-11
| | | | | | | | | The fourth substream is being discarded, since its not raw audio data, but an encoded Atmos stream which needs a specialized decoder.

* movenc: Support setting fragment_index before the moov atom is writtenMartin Storsjö2015-03-10
| | | | | | | | | | This way, the caller doesn't need to coordinate setting the option after the moov atom has been written. The downside is that it is no longer possible to use the option for checking whether the moov atom already has been written, but a caller is able to keep track of that by other means anyway. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Don't rely on the fragment index for vc1 info gatheringMartin Storsjö2015-03-10
| | | | | | | | The previous use of the mov->fragments field, for determining whether written packets were part of the first fragment or not, didn't work as intended when using the empty_moov flag. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc_mpegts: Set chain->rtp_ctx only after avformat_write_header succeededMartin Storsjö2015-03-10
| | | | | | | | | | | | By making sure we at each time only have one pointer set, either a local variable or one in the context, we avoid potential double frees in the cleanup routines. If chain->rtp_ctx is set, it is closed by calling avformat_write_trailer, but that shouldn't be called unless avformat_write_header succeeded. This issue was pointed out by Andreas Cadhalpun.

* rtpenc_mpegts: Free the right ->pb in the error path in the init functionMartin Storsjö2015-03-10

* FATE: add support for testing hwaccelsAnton Khirnov2015-03-10

* avconv: do not abort immediately if initializing hwaccel failsAnton Khirnov2015-03-10
| | | | | | exit_program() will try to free the decoders, which is not a good idea from within get_format(). Return an error instead.
* libvpx: Fix mixed use of av_malloc() and av_reallocp()Vittorio Giovara2015-03-09
| | | | | | | | This buffer is resized when vpx_codec_get_cx_data() returns a VPX_CODEC_STATS_PKT packet. CC: libav-stable@libav.org Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* siff: Use the correct type for packet size variablesVittorio Giovara2015-03-09
| | | | | | | | The avio functions used here return an unsigned value. Also reduce a variable scope. CC: libav-stable@libav.org Bug-Id: CID 1258461
* matroskaenc: Also validate chapter end timeVittorio Giovara2015-03-09
| | | | | | | This prevents it to be written as unsigned. Also add an error message. CC: libav-stable@libav.org Bug-Id: CID 1265717
* rtpdec_hevc: Drop extra sanity check for size of input packetVittorio Giovara2015-03-09
| | | | | | | In this case len is always at least 3, since it is checked against RTP_HEVC_PAYLOAD_HEADER_SIZE + 1 before entering the switch block. Bug-Id: CID 1238784

* movenc: Set tfhd default sample flags based on actual samples, if possibleMartin Storsjö2015-03-09
| | | | | | | | | | This avoids assuming that e.g. audio samples are marked as sync samples. This allows omitting the sample flags from trun, if the default flags happen to be right for all the samples. Signed-off-by: Martin Storsjö <martin@martin.st>

* vorbis: Check the vlc value in setup_classifsLuca Barbato2015-03-08
| | | | | | | | The valid returned values are always at most 11bit. Remove the previous check that assumed larger values plausible and use a signed integer to check get_vlc2 return values. CC: libav-stable@libav.org

| | | | | | | | a876585215 had the unintended side effect of returning AVERROR(ENOMEM) when track->entry is zero, while the code intentionally wants to continue in that case. Signed-off-by: Martin Storsjö <martin@martin.st>
* dashenc: Update extradata for mov muxerTimo Rothenpieler2015-03-06
| | | | | | | | | | | | The mov muxer already supports picking up extradata that wasn't present during the avformat_write_header call - we just need to propagate it. Since the dash muxer uses delay_moov, we have time up until the first segment is written to get extradata filled in. Also update the codec description string when the extradata becomes available.

* avformat/adxdec: set avctx->channels in adx_read_headerAndreas Cadhalpun2015-03-05
| | | | | | | | | It is used in adx_read_packet, which currently depends on the decoder/parser setting this value between reading the file header and demuxing the first packet. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* rmenc: limit packet sizeAndreas Cadhalpun2015-03-05
| | | | | | | | | | | | The chunk size is limited to UINT16_MAX (written by avio_wb16), so make sure that the packet size is not too large. Such large frames need to be split into slices smaller than 64 kB, but that is currently supported neither by the rv10/rv20 encoders nor the rm muxer.

* webp: validate the distance prefix codeAndreas Cadhalpun2015-03-05
| | | | | | | | | | | According to the WebP Lossless Bitstream Specification the highest allowed value for a prefix code is 39. If prefix_code is too large, the calculated extra_bits has an invalid value and triggers an assertion in get_bits.

* rtpdec_qt: Use a local variable instead of RTP_FLAG_KEYMartin Storsjö2015-03-05
| | | | | | | | The only case where RTP_FLAG_KEY actually is needed is in RDT, where such a flag needs to be passed via the rtpdec parse function's flags parameter. Signed-off-by: Martin Storsjö <martin@martin.st>
